SAEDNEWS: If you want to prevent mushrooms from turning black and spoiling for a long time, you can use freezing or keep them in their original packaging so that you can always use fresh mushrooms.
According to SAEDNEWS, Mushrooms can be one of the most difficult foods to store because they quickly absorb a lot of moisture and begin to spoil. You should keep mushrooms in their original packaging as much as possible, or store them in a paper bag or paper towel, or freeze them, as all of these methods can help keep mushrooms fresher.
If you want to store the fresh mushrooms you have purchased for a long time and preserve them so you can use them whenever you like, you can use the freezing method for mushrooms explained in this home care section.
1. Keep mushrooms in their original packaging
If you are not going to use your mushrooms right away, it is best to keep them in their plastic packaging, as these packs usually have small holes that allow excess moisture to escape without drying out the mushrooms.
2. Cover the packaging carefully
If you only need a small amount of mushrooms, make a minimal opening in the original plastic wrap. After removing what you need, reseal that area to prevent air from entering the package.
3. Store mushrooms in the refrigerator
Once you bring mushrooms home, place them in their original packaging inside the refrigerator. Refrigeration slows down spoilage, and using this method, fresh mushrooms can last for about one week.

1. Place mushrooms in a paper bag
If you do not want to keep mushrooms in their original packaging, you can store them in a paper bag instead. The size of the bag depends on the amount of mushrooms, but brown paper bags are generally the best option. You can also wrap them in a slightly damp paper towel before placing them inside the bag.
2. Leave the paper bag open
Do not close the top of the bag. Leaving it open helps maintain balanced humidity. The bag will absorb some moisture while still preventing the mushrooms from becoming too damp.
3. Store the bag in the refrigerator
Keep the paper bag of mushrooms in the refrigerator, preferably in one of the drawers. This helps prevent the mushrooms from absorbing odors from other foods, and the drawers are designed to keep fresh vegetables properly stored for longer. Using this method, mushrooms can last about 7 to 10 days.

1. First, clean the mushrooms
If you do not plan to use fresh mushrooms within a week, you can freeze them for longer storage. Start by rinsing the mushrooms under water, then let them air dry. You can also spread them on paper or a towel to absorb excess moisture.
2. Brush the mushrooms
Once the mushrooms are almost dry, gently clean them using a paper towel or a soft vegetable brush. This helps remove any remaining dirt or impurities.
3. Sauté the mushrooms
Before frying, chop the mushrooms and mix them with 1–2 tablespoons of olive oil along with some salt and pepper.
4. Let the mushrooms cool
After cooking, allow the mushrooms to cool completely before freezing. Spread them out on a plate so they cool evenly.
5. Freeze in plastic bags
Once the mushrooms are cool, place them in plastic freezer bags and store them in the freezer. Pre-cooking them before freezing helps prevent them from absorbing excess moisture.
